This property have a total of 16 flats and it is almost complete. I stay in New Delhi but I bought this house for my parents. I have been running after this builder for registry but they keep on giving us different stories. We bought this flat at the rate of Rs. X per sq ft now this builder is saying that the valuation of the property will be on different rate and that this rate differs month to month.Kindly help me and let me know the process of the registration. The property is under Sonarpur Municipality.
